In contrast, STL files describe the geometric characteristics of three-dimensional objects only, lacking descriptive information like color or material.

These models contain color and form information. CAD programs generate STEP (standard for the exchange of product data) files, which are an ISO standard exchange program that ensures that CAD designs can be opened and edited on a variety of programs by international users. This article covers the essentials of preparing your STEP files for printing.Ĭomputer-aided design (CAD) is a widely used technology for translating complex designs to manufacture-ready instructions for a machine. However, not all programs allow for the direct export of print-ready files. CAD programs are powerhouses for designing 3D models.
